Your Device Has Been Unlocked And Can’t Be Trusted


If you’ve ever encountered the message “Your device has been unlocked and can’t be trusted” on your Android device, it can be concerning and confusing. This message typically appears during the boot-up process and may lead to questions about your device’s security. In this article, we’ll explain what this message means and what you can do about it.

Understanding the Message:

  1. Device Unlocking: The message “Your device has been unlocked” usually refers to unlocking the bootloader of your Android device. A bootloader is a piece of software that loads the operating system when the device starts. Unlocking it allows users to make significant changes to their devices, such as flashing custom recoveries or installing custom ROMs.
  2. Can’t Be Trusted: The “can’t be trusted” part of the message means that the device’s security status has been altered, often due to unlocking the bootloader. By unlocking the bootloader, you may have compromised some of the security features put in place by the manufacturer and Android operating system.

Why Does It Occur?

The message appears as a security feature and a reminder to the user. Here are a few reasons why it might occur:

  1. Bootloader Unlock: As mentioned earlier, if you’ve unlocked your device’s bootloader, it is no longer in its factory-locked state. Bootloaders are locked by manufacturers to prevent unauthorized system modifications.
  2. Custom ROMs: Installing a custom ROM on your Android device often requires unlocking the bootloader. Custom ROMs are alternative versions of the Android operating system, and they can change how your device operates.
  3. Rooting: Rooting your device, which gives you superuser (administrator) access, can also trigger this message. Rooting can potentially expose your device to security risks if not done carefully.

What to Do When You See This Message:

Seeing this message doesn’t necessarily mean your device is compromised or insecure. However, it’s crucial to be aware of the potential risks and steps you can take:

  1. Be Cautious: If you see this message and you haven’t intentionally unlocked the bootloader or rooted your device, it’s essential to investigate further. Unauthorized bootloader unlocking or rooting can pose security risks.
  2. Verify Source: If you’ve unlocked the bootloader or made changes intentionally, ensure that you trust the source of the custom ROM or rooting method. Using reputable sources and following guidelines can minimize potential security concerns.
  3. Regular Updates: Keep your device’s operating system and security patches up to date. Manufacturers and Android continually release updates to enhance security.
  4. Reset to Factory Settings: If you’ve encountered the message and are concerned about your device’s security, you can perform a factory reset to return your device to its original, locked state.
  5. Contact Support: If you’re uncertain about the message and its implications, consider reaching out to your device manufacturer or the Android support community for guidance.


The message “Your device has been unlocked and can’t be trusted” is a reminder of the importance of device security. While unlocking the bootloader or making system modifications can be legitimate and useful for advanced users, it’s crucial to do so thoughtfully and from trusted sources. Understanding the risks and potential consequences of these actions is key to keeping your Android device secure and functioning optimally.
